DESCRIPTION:

The Model 8800V laser flashlamp controller provides variable pulsewidth pulses for pumping solid-state lasers.
The microprocessor provides the flexibility and convenience of software control. The system status is presented on an easy-to-read LCD graphics display.
The Model 8800V can be configured to include software, simmer supply and a capacitor charging power supply to form a complete turn-key laser flashlamp controller in a 19” rack mounted assembly.
The 8800V can also control two independent PFN/power supply outputs for Osc/Amp laser applications.
 To sel ect the correct 8800V model for your application, use the two graphs at the bottom of the page. Knowing the lamp impedance parameter, KO, and the Joules per millisecond desired in the application, determine the graph which best fits the requirement. Once the selection is complete, the Y axis will determine the number (one or two) of HV switches required and the corresponding area under the desired charge-voltage curve (400V, 800V or 1000V) will determine the maximum charge voltage required. The average power required is determined by the product of the Joules per pulse and the pulse repetition frequency. Please refer to the 8800V applications note for additional information on pulsewidth, PRF, and droop limitations of electronic PFNs. For custom configurations, contact our application staff for details.

For example:

1. Lamp impedance parameter (KO) = 28Ω-A½.

2. 350J per pulse, 1mS pulsewidth at 3Hz is desired for the application.

3. Calculate the Joules/mS by dividing the Joules per pulse by pulsewidth required.

4. Find the lamp KO on horizontal axis of graphs at bottom of page. Find the required J/ms on the vertical axis. Select the graph labeled “Joules/mS using Two HV Switches”. This graph will accommodate the required 350J/mS with KO of 28. Also note that the intersection of KO and desired J/mS falls just below the 800V curve on this graph.  

5. Calculate the average power required from the power supply with the product of Joules per pulse and pulse repetition frequency. P=350J x 3Hz = 1050J/S or watts.

Therefore, the application requires an 8800V with two HV switches, charge voltage of up to 800VDC and 1050W minimum power supply.

AMI’s complete model number is: 8800V-2-5-800C-S-2-D

Note: The graphs below represent typical performance and do not account for lamp risetime and droop over pulsewidth. For narrow pulse applications (~100-200μS), the energy “calculated” and energy “measured” by the microprocessor will differ due to lamp risetime delay. This delay is due to the dynamic properties of each lamp and will vary from lamp to lamp. For long pulsewidth applications, allowable droop should be considered on a case by case basis.
